PEG-9 ISOSTEARATE

Description

PEG-9 Isostearate is a versatile emulsifier and surfactant commonly used in skincare and cosmetic formulations. This synthetic ingredient is derived from the esterification of isostearic acid with polyethylene glycol (PEG). Its molecular structure consists of a hydrophobic isostearic acid chain attached to a hydrophilic PEG chain, allowing it to effectively bridge oil and water phases in product formulations.

In skincare applications, PEG-9 Isostearate functions primarily as an emollient and emulsifier. It helps create stable emulsions, improving the texture and consistency of creams, lotions, and other skincare products. This ingredient enhances the spreadability of formulations, providing a smooth and silky feel upon application. Additionally, PEG-9 Isostearate can act as a mild surfactant, aiding in the cleansing process without overly stripping the skin's natural oils.

Due to its emollient properties, PEG-9 Isostearate can help improve skin hydration by forming a protective barrier that reduces transepidermal water loss. It is generally well-tolerated by most skin types and is often used in products designed for sensitive skin. However, as with any synthetic ingredient, patch testing is recommended for individuals with known sensitivities.
